José's Ultimate Gin & Tonic

In a wide-rimmed rocks glass or stemless red wine glass, add gin. Place large ice cube in the glass, and top with lime wheel. Express, or squeeze, the lemon peel on the inside of the glass to release its oils, and place it on the ice cube. Place the three juniper berries on top of the cube, pinching one to release its aroma. Slowly add tonic water to taste -- half the bottle for a stronger drink, more for a smoother one.
